    Abstract: A method of controlling transfer power of an image forming apparatus includes: determining a sensing feedback voltage by applying a set sensing current and measuring a first output voltage during a time period before an image is transferred to a transfer medium; measuring humidity and comparing the measured humidity with a set value; setting a target voltage based on the determined sensing feedback voltage when the measured humidity is equal to or higher than the set value; and adjusting the transfer current to apply the target voltage during a time period in which the image is transferred to the transfer medium.
